Both Engines Die Over the Pacific
Jun 4, 2015 09:14:09 #
Imagine you're flying over the Pacific Ocean and both of your Rolls Royce engines stop turning - for 25 minutes. That's what happened to a Singapore Airlines Airbus a few weeks ago.

I saw a similar situation on YouTube last night. A British jet was seconds away from touching down when both engines stopped. They managed to make a relatively safe landing with no engine power. In that case, the problem was ice in the fuel. Outside temperatures on their route were as low as -70° F. Although the plane had fuel heaters, while the engines were basically idling along at cruising speed, ice began to form on the inside of the fuel lines. When the pilot called for more power to land, the rush of fuel dislodged the ice and clogged the fuel heater. A modification to the heater should prevent that from happening again. Fingers crossed.

Anyone who believes that plane glided for 25 minutes with no power will no doubt vote democratic in the next election...

There have been a number of airliners that have lost full power and flown for huge distances. The Air buses in particular seem to be quite good at gliding.
Air Transit Airbus in particular glided for a distance of 120 kilometers for 19 minutes over the Atlantic before safely landing in the Azores.
The "Gimli Glider, an Air Canada 767 lost both engines over the Great Lakes and glided for miles before safely landing at an abandoned Air Force base.
If handled carefully, these planes can glide for huge distances without power.

And I recall a 747 over Alaska that flew into a plume of volcanic ash in the dark and lost all power and descended to about 5,000 feet before they regained power.

It is known as glide ratio. Due to the force of gravity the plane will still maintain some forward speed due to going down through the air. This speed while not enough to provide lift to gain altitude will cause the plane to descend at a given ratio, for instance 15 ft. Forward for each foot of descent. At that ratio, just an example, a plane at 35, 000 feet would be able tp cover a great distance before having to meet up with Mother Earth.

I remember a story back in the early days of the U-2 before they were public knowledge when one of flamed out about 200 miles out, somewhere off Cape Hatteras. The Pilot radioed a Mayday and the nearest airport told him they would scramble a rescue unit; the pilot responded with something to the effect of "Never mind, I'll glide in". Knowing it was a jet, but not what kind, the tower didn't believe him. He landed at some commercial airport in NC, I believe, but couldn't make it to a secure Military airfield. That was the first knowledge and sighting by the general public of the "Spy Plane".
